In conclusion, we decided that, depending on the mass of the object, the bungee cord will allow a different drop. For example, the ball was 58g and the car was 37g. The ball dropped a farther distance than the car did because it weighs more. The tennis ball fell an average of 3.06 meters with an average acceleration of 5.42 m/s/s. The marker fell an average of 2.48 meters at 5.8 m/s/s and the car fell 2.82 meters at 5.62 m/s/s. Because of the different masses, they dropped at different times. The marker took .66 seconds to drop and the car took .715 seconds. The longest was the ball which was .76 seconds. Compared to a person on a bungee drop, the lighter the person is, the quicker he/she will drop but they wont go as far down as a heavier person. The effect that the change of the object has on the bungee drop is the acceleration, time and distance; they all depend on the mass of the object.

BUNGEE DROP
Goal: To determine the effect that the change of the object has on the bungee drop.
Questions we will answer (for each object):
How far does the object fall with the bungee cord?
How long does it take for the object to drop?
What is the acceleration of the object?
Materials:
1 Rubber band cord
2 Tape measure
3 Camera
Objects:
1 Tennis Ball
2 Expo Marker
3 Toy Car
Procedure (Part 1):
1 Build bungee cord
2 Measure the height from floor to area of dropping
3 Mass the objects
4 Two trials of the drop (by video recording)
5 Upload video
6 Use data and equations to find answers to the questions
Data (Part 2):
Height of drop: 12 feet
Mass (in grams)
Ball
Marker
Car
Trial 1
Time
Distance
Acceleration
Ball
Marker
Car
Trial 2
Time
Distance
Acceleration
Ball
Marker
Car
Calculations/Equations:
To find velocity: distance/time, and To find acceleration, divide the velocity by the time.
- Ball T1= 2.997/.82/.82= 4.46 m/s/s- Ball T2= 3.12/.7/.7= 6.37 m/s/s
- Marker T1= 2.44/.71/.71= 4.84 m/s/s
- Marker T2= 2.515/.61/.61= 6.76 m/s/s
- Car T1= 2.79/.77/.77= 4.71 m/s/s
- Car T2= 2.845/.66/.66= 6.53 m/s/s
